I just noticed the difference in the element formation between the 1.1 and the 1.2 DTD for Tag Library Descriptors (tlibversion (1.1) vs tlib-version (1.2) etc.). I would assume that the correct version to use is 1.2 DTD, but I cannot be sure from reading the exam requirements. Most of the study notes and books use the old version. Could someone please let me know which one to study. Thanks, Clark

Mark, I just reviewed Ersin's info. It great! However, unless I'm missing something, it seems to be for setting up the web.xml Deployment Description. What I am asking about is the DTD to set up the .tld file for a custom tag library. Has the exam been updated to use the new hyphenated tags in the 1.2 DTD? Regards, Clark

Ah, the custom tag library. You do need to know that one too. Actually we are lucky that is it short. I know I pretty much learned it from the notes. Like Ken's or someone elses. Let's see you have the Tag tag, and underneath that you have the attribute tag that has some child tags. The attribut child tags are <rtexprvalue> for saying whether this attribute can be determined at run-time. <required> states that it must be in there. <body-content> states what would be the acceptable stuff in between the tag. the default is JSP. There really isn't much more that you really need for the exam. Well that's based on the questions I received. Good Luck Mark

Actually p.237 is the DTD for JSP 1.1 TLD (the one for 1.2 is on p.225). However, it does say something important, it starts:

This appendix includes the DTD for a tag library descriptor using JSP 1.1. All JSP 1.2 containers are required to accept such a TLD.

So, I guess that unless you get a question which explicitly mentions 1.1 or 1.2 (or refers to a particular DTD) then either version should be acceptable :-)

If it helps, the title on that page says: "APPENDIX JSP.C DTD for TagLibrary Descriptor, JSP 1.2" :roll: You might want to check what version of Specs you have. - satya

Ok, to be precise ... the page which has "225" printed on it, and which Acrobat refers to as page 237 ... Anyway, point is that the 1.2 spec mandates that containers must accept 1.1 and 1.2 versions of the DTD.
